摘要 |
Multiparadigm methods to span the scales from quantum mechanics to practical issues of functional nanoassembly and nanofabrication are enabling first principles predictions to guide and complement the experimental developments by designing and optimizing computationally the materials compositions and structures to assemble nanoscale systems with the requisite properties. Materials with low dimensions, i.e. carbon nanotubes, graphene and derivatives have generated an enormous impact on next generation nano devices owing to remarkable physical properties. In this talk, we employ multiparadigm approaches to investigate the growth mechanism of functional graphene derivatives and related layer materials, to unravel the versatile physical properties, esp. the optical properties manifested by strong electron-electron Coulomb interaction due to the reduced dimensionality, which influences the behavior of exciton in materials with low dimensions. |
